How can I prevent a cold spreading to everyone in the family? Cold and flu viruses are spread by transferring droplets of fluid from your nose or mouth. You may prevent this by: • Keeping your hands away from your eyes, nose and mouth. • Hand washing with plenty of soap and water. • Not sharing cups or cutlery. • Using paper tissues to blow your nose and throwing them away after use. Remember to wash your hands after covering your mouth for a sneeze. • Making your home a smoke-free zone as smoke can irritate the nose and lungs and may increase a child’s susceptibility to a cold.
